In a desert setting, a water cooler is used to cool and saturate a stream of hot, relatively dry air. Air at 39°C and 25% relative humidity flows to the cooler, where a 100 mL/min stream of water at 30°C is sprayed in a fine mist into the air stream. The air leaves the cooler at 100% relative humidity (i.e., saturated) and temperature T, and the un-evaporated water leaves the cooler at the same temperature T (i.e., in equilibrium with the exiting air stream). The pressure of all streams is 1 atm. a. Draw and completely label the flowchart for the process. b. Carry out a degree of freedom analysis to show that the system is completely determined. c. Simplify the energy balance for the system, and identify the necessary values needed for solution of the energy balance. d. Determine the following: i. Outlet temperature T (°C) ii. Mass flow rate of both components (air, water) in the two outlet streams iii. The fraction of the liquid water feed that evaporates In a desert setting, a water cooler is used to cool and saturate a stream of hot, relatively dry air.
